Coal power, using fossil fuels.

1). (c). The heat from deep in the Earth is the renewable resource.

2). (c). The natural gas is the non-renewable resource.

3). (d). The energy from the sun, collected with solar panels, is the renewable resource.

4). (b). The energy in the flow of water through the dam is the renewable resource. If you analyze it in detail, it turns out to be solar energy.

**Answer:**

**The car will travel a distance of 17.45 meters.**

**Explanation:**

Given:

Initial velocity = 0

Final velocity = 7.6 m/s

Time taken = 4.6 s

**Acceleration = (Final velocity - Initial Velocity )/time**

We have to calculate total distance traveled by the car.

Let the distance traveled be 'd'

Equation of motion:

Plugging the values.

⇒

⇒

⇒

**The car will travel a distance of 17.45 meters for the above case.**

**Answer:**

The buoyant force is 9.8 N.

**Explanation:**

The buoyant force acting on the material is called upthrust, and can be determined as;

Upthrust = density of liquid x volume of object x gravitational force

So,

density =

⇒ mass = density x volume

= 4230 x 0.001

= 4.23

mass of the material = 4.23 kg

But,

weight = mass x gravitational force

weight = 41.5 N, and mass = 4.23 kg, then;

41.5 = 4.23 x g

g =

= 9.811

g = 9.8 m/

Upthrust = 1000 x 0.001 x 9.81

= 9.81 N

The buoyant force is 9.8 N.
